Abstract

Yunak Fay Zonu, Batı Anadolu’nun sismik olarak aktif çöküntü alanlarından birisi olan Afyon Akşehir Grabeni (AAG)’nin kuzeydoğu bölümünde yer almaktadır. Bölgede gerçekleştirilen saha ağırlıklı çalışmalar sırasında Yunak Fay Zonu içerisinde kalan 4 segment ilk defa 1/25.000 ölçekli olarak haritalanmış, Cebrail, Üçkuyu, İncirli ve Ayrıtepe Segmentleri olarak ilk defa adlandırılmış, geometrik, kinematik ve aktif tektonik özellikleri ilk defa analiz edilmiştir. Saha çalışmaları ile elde edilen bulgular, çalışma alanında uzunlukları 3 km ile 18 km arasında, genişlikleri 300 m ile 3 km arasında değişen, KKD-GGB, KD-GB ve DB uzanımlı ve 5,6 ile 6,7 moment büyüklüklerine kadar deprem üretme potansiyellerine sahip fayların varlığına işaret etmektedir. Gerçekleştirilen paleogerilme analizleri, bölgede yer alan fayların Miyosen-Erken Pliyosen'de etkili olan genel olarak K-G yönlü çekme gerilmesi ile ilişkili D-B yönlü sıkışma gerilmeleri etkisi altında saf doğrultu atımlı faylanma ile oluştuklarını, Pliyo-Kuvaterner döneminde etkili olan çekme gerilmesi tektonizması sırasında ise D-B, KG ve KD-GB arasında değişen çok yönlü genişlemeli (multi-directional extension) tektonik ortam içerisinde eğim/oblik atımlı normal fay şeklinde çalışarak reaktive olduklarını ortaya çıkarmıştır. Bu çalışmada ilk defa tanımlanan Akşehir Alt Grabeni, eğim atımlı Yunak ve Mevlütlü Fay Zonları ile kontrol edilmektedir ve Sultandağı Fayı’nın düşen bloğu üzerinde çapraz graben niteliği sunmaktadır.

Active Tectonics and Kinematic Analysis of Yunak Fault Zone, Afyon Akşehir Graben

Abstract

The Yunak Fault Zone is located in the northeast part of the Afyon Akşehir Graben (AAG), which is a seismically active graben in Western Anatolia. During field-based studies, four segments within the Yunak Fault Zone were mapped for the first time at a scale of 1/25,000, and named as the Cebrail, Üçkuyu, İncirli, and Ayrıtepe Segments. Their geometric, kinematic, and active tectonic features were analyzed for the first time. The findings obtained from field studies indicate the presence of faults with lengths ranging from 3 km to 18 km and widths ranging from 300 m to 3 km, with orientations varying between NNE-SSW, NE-SW, and E-W, capable of producing earthquakes with magnitudes ranging from 5.6 to 6.7. Paleostress analyses of fault slip data reveal that the NE-SW trending faults in the region were formed by pure strike-slip faulting under the influence of a N-S directed tensional and E-W directed compressional stress regime during the Miocene-early Pliocene. However, during Plio-Quaternary extensional tectonics in western Anatolia, they were reactivated as dip/oblique-slip normal faults within multi-directional extensional tectonics in E-W, NE-SW, and NNE-SSW directions in the northeastern part of the AAG. In this study, the newly identified Akşehir Sub-Graben is controlled by the NE-SW trending dip-slip Yunak and Mevlütlü Fault Zones and exhibits characteristics of a cross-graben on the hanging wall block of the Sultandağı master fault.
